Marilla’s center stands about 940 ft above sea level. Within three miles the land runs from 760 ft to 1,180 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Briar Hill, about 1,740 ft, 10 miles east.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 8 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Marilla reaches Lake Michigan by way of Cedar Creek, Bear Creek and the Manistee: about 35 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marilla; river miles along the main stem, rounded.
